are there any minimums do captains have to have a set number of teammates or could I literally just take 1 or 2 from an individual captain

No minimums for teammates from each individual captain. The only specific roster rule is that you have to use the strike year for each of your captains. Other than that normal random captain rules apply.

There was a problem with the captains since alleyviper got Nolan Ryan twice. I decided that rerolling 1972 was the fairest way to alleviate the problem. Alleyviper got Nolan Ryan again (haha!) so I had to reroll a third time. Here are the final captains:

I got stuck with Rick Monday only has230 abs and I am forced to use him. Shouldn't we have picked players with full seasons at least? Normally wouldn't care but I got hamstrapped on a 90 mil cap with 13 mil to Carlton on a reroll and now a bench player with 2 mil. Hardly seems fair at a 90m cap. Could hide it with 100 mil but 90 mil that is 2 albatrosses

Setting minimums and maximums on salary/ABs/IPs is a good idea and something I'll consider in the future if I run this again or something like it. That Rick Monday is at least a very good season (if very short on PA) and hopefully you should be able to find a platoon partner for him.
